To all whom t may concern:

^ Be it known that we, ABRAHAM Kirmes,

a citizen of the United States, and a vresident of the borough of Brooklyn, city of New York, in the county of Kings and Statev of New York, and MAX PAUL NEUMANN, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the county of Kings and'State of4 New York, have invented a certain new and Y rollers adapted to bend over the edges of a strip of sheet metal, with a series of upper and lower "rollers which serve to force said bent-over edged strip forward between lateral guides, a portion of said strip together A with:y one of said be'nteo'ver edges being thereby forced over a series of anti-friction rollers which have ya gradually yincreasing inclination from the side edges of certain of said upper rollers whereby' said portion of said strip'is bent up to a position nearly at a right angle to the plane of the strip;

TheA invention further consists inv Vprovidinga fixed guide against which the edge of said bent portion of the bent-over edged strip bears, together with a series of'antifriction rollers which Vare successively in-V clined from a position at right angles .to the plane of the strip to an acutely inclined position relative thereto, so that forward movement of said strip causes said bent portion ofthe strip to be further bentito an acute angle to the plane of the strip.

f rIn the accompanying drawings: *Figure 1 is a plan view of the machine, showing the passage therethroughof a strip of sheet metal, and the operation of bend-4 ing the same toform 'the metal binding.

Fig. 2 is a longitudinal vsection on the i line I I--II of Fig.

Fig. 14 is a perspective view of the strip of sheet Ymetal after it has beenl bent by passage through Y the machine.

Fig; 15 is a detail view showing the strip further bent when applied as metal binding toa suit case.

Journaled in the frame 1 of the machine, is a driving shaft 2,to which is secured a gear wheel 3. ,Greark wheel 3 is in mesh with a gear wheel 4, secured to a shaft 5,to which a roller 6 ris secured.v In mesh with gear wheel 4 is a gear wheel 7, secured to a shaft 8, to which a roller 9 is secured. Also in meshl with gear wheel 4 is a gear wheel 10, which is journaled on a fixed shaft 11. In mesh with'gear wheel 10 is a gear wheel 12, secured to a shaft .13, to which a roller 14 is. secured. Gear wheel 12 is in mesh with aV gear wheel 15,' secured to a shaft 16, to which a roller 17 Vis secured.

In mesh with gear wheel 3, is a gear wheel 18, secured to a shaft 19, to which a roller 2O is secured. Gear wheel 18 is in mesh with a gear wheel 21, secured to a shaft'22 to which a roller 23 is secured. Also in mesh with gear wheel 18 is a. gear wheel 24 which; is journaled on a fixed shaft25. In mesh `with gear wheel 24 is a gear wheel 26 secured toV a shaft 27, to which is secured aroller 28.y Gear wheel 26 is in mesh with a gear wheel 29, secured'to a shaft K A strip of sheet metal 34 may be lplaced upon a horizontal support 35, and passed forward between lateral guides 36 and vbetween'the upper and lower rollers of each of the seriesfof pairs, whereby forward movement is imparted'to the strip. e Thev rst pairof rollers 14 and 17 is provided with cooperating inclinedsurfaces 37 and 38, adapted for bending theedgesof the strip to obtuseangles `from the strip. YThe second pair of rollers 6 and 9 is provided Y' with cooperating right angular surfaces 39 and 40 adaptedfor further bendingthe -edges'of the strip Yto right anglesv therefrom.

The third pair of rollers 2O and 23 isV adapted for further bending the edges to 'acute angles from the strip, this being accomplished by means of inwardly linclined surfaces 41' formed on the upper roller 23. `The fourth` pair of rollers is adapted for further bend-1 ing the edges so that they standparallel with the strip', thereby forming'the folds a. rlhis isaccomplished by means of cylindrical surf faces 42v formed on the upper roller 31,' the folds a being forced between guiding shoulders 43 and 44 Yformed on said pair of rollers; Y The strip having the edges bent' in the manner described 'and -moved vforward by means of the feed rollers, passes onto a' hori- Y Zontalfsupporting bar 45; and, between lateralI guide 'bars 46and `47 against' Vwhich the two edges of the bent-over edged strip bear# Y ,v Located at short distances apart through-- out the length of support45- are rollers 48 which 'support the strip 34, slightly 'above the' support 45.Vv Each roller is secured toa shaft 49fjoiirnaled^`in bearings 50, which are Inovedupward by means of springs 51. w Secured to each shaft -49 isa gearwheel 5 2 in p mesh with a Vgear wheelf53 for-ming -part of lchain wheel secured tothe driving shaft 2. A series 'of idle pulleys 6()l serve to hold th'elchairr in engagement with theteeth of ychain wheelsz57.- Oneofthe pulleys v6() is mounted on* a slide 61,"which is free to 'move u, in 'guides .62 and"` adjusted by means of a .Screw 63, so'that slack inthe chain'may be taken up when necessary to secure engagement of the chain withl the chainfwheels- 57.

It will beevident that rotation of the drivl 'mg shaft 2in vthe'direction indicated jby the arrow will cause rotation of the-shaping fe'edr'ollers', andthe' series of pairs of rrollers 48and v56 in a direction to cause continued forward movelnentbof the stri 34 between the'lateral guide barsl 46 and 4 Y 1 'As'shown. in Fi-g. 7 the side edge 64 of the first upperroller 56 stands a short distance bears against the guide`bar'46. y v Y Y i A series"ofantiff'ction rollers 65,-'66an1d from the bent-'over edge `of the strip. that, y Y' at the inclination required to cause thev fold K I) to/be. formed in strip, lthereby completing Y Y 67, are placed belowthis' portion of the stripY `and are inclii'iedfnpward from the sideedge .64 ofk upper roller 56, the V'roller 65"being toward the` supporting bar 45.

slightlyY inclined from the' plane of the strip, roller 66 being inclined more than roller 65, and roller 6,7 being inclined mo-re than roller 66:'V While therollers 48 and56'mo've`the strip forward, the portion ofthe stripriding onthe differently inclined antifriction rollers'65, 66 and 67 is forced up against Ythe edge 64 of the upper roller 56, thereby causing a crease to be formed in the strip, as shown in Fig. 8. The side edge 68 of the second upper roller 56 stands in line with the side edge 64 oftheiirst upper roller 56, and a seriesy of antifriction:rollers 69, 7 0 71 and 17 2, placed below the portion of the 'strip extending to guide bar 46 are successivelyV inclined from-edge 68 of the second` upper roller 5,6 togreater angles than that of antifriction roller 67, so that as the strip is moved forward,vsaid bent portion of the stripv is 4further bentagainst the edge 6 8- of said second upper roller, as shownin Fig. 9. The side edge 73 of the thirdiupper roller 56 also stands vin" line with'the side edge 64 of the first upper roller 56, and a series of antifriction rollers 74,;7 5, 76 and 77,'placed sov below sa-idbent portion of the strip are succ'essively inclined from edge 7 3 of the third upper roller 56 to greater angles than that of antifriction roller 72so that as the strip vis moved forward, said bent portion ofthe strip is :further bent' against said edge 73of the thirdupp'er roller, untilisaid portion of the stripstands nearly. at aright'angle Y tot', the edge of the-strip; {as-shown Vin.
